Here's the thing.
Its a predator decoy, turns out you can't use it as a baseball or a hockey puck, can't use it as a wedge to keep your camper from rolling down a hill. Button pushes easy, you don't need to hit it with a hammer.
Yea, trying to force it into rock hard ground isn't the most intelligent idea either.
If you are lacking common sense, you may want to turn yourself a housing out of steel bar stock, go ahead and turn yourself a 2" stake while your at it. This way you can use it as a bit for your jackhammer should the need arise.
In other words, it's a decoy, use it as such and you'll be a happy guy, treat it like garbage and it becomes such.
